With an easy bolt-on installation, the KR Axle-Back Kit from MRT replaces your S550’s factory mufflers with an intense, aggressive sound. With a perfect fit and finish, how could you say no to picking up these muffler deletes for your V6 or EcoBoost?

These pipes are designed and manufactured in the USA and made of CNC mandrel bent 304 stainless steel tubing. That means that this axle-back kit will without a doubt stand the test of time. With a loud, aggressive exhaust note, these pipes will not only improve your Mustang’s exhaust flow, but also save your Pony a few pounds in comparison to stock mufflers.

*Will not fit 2019 or 2020 EcoBoost Mustangs that are equipped with the Active Exhaust Option from the factory.

Rated 5 out of 5 by from Very loud, sounds similar to a v8 I bought this muffler and paired it with the flowmaster y pipe resonator delete and it is very loud. You will get pops on revs and it is one of the best sounding exhausts for the price.
